Hi, i need to study Mathematics from scratch. I didn’t learn any math at school. I’m from a EU country, not UK.

I have a hard time finding math books that use the metric system online. I try’d openstax, but those books use imperial dogshit. https://openstax.org/ I try to scavenge anna’s archive. But all of them imperial. And all UK Secondary School books online are incomplete. I can’t just buy/import them because i have not been in school for over a decade. Only teachers can buy them.

I need pure metric Math e-books for prealgebra, algebra 1&2, Trigonometry, Geometry, Precalculus, Calculus. I want to put them om my e-reader with wacom stylus, so i don’t need to buy paper.

If i have to use imperial measurements for longer than an hour, my brain will explode. 🤯 I’m not looking forward to converting and typesetting hundreds of books in LaTeX on Arch linux.

Which books should i get? Only complete books.

    I’m sorry, but is your problem really with fractions? In most Geometry-and-up textbooks, the units don’t really matter - they’ll almost always be decimals, unless where emphasizing fractions or conversions is the point - and you can skip those sections/problems easilly. The ratios in Trig and Polar coordinates can’t be helped - a metric degree-minute-(decimal)second angle measurement is literally just that.

    Thinking about it, you might have better luck with Chemistry-oriented math textbooks, not because there’s no conversions or fractions, but because Avogadro’s number really drives home the point of how messy metric still is, outside of the finished textiles industry, and how messy any measurement system always will be. The boon of metric is more that your length, volume and wieght measurements don’t change based on context, not that it eliminates all fractions and conversions.

    That said, for a more-metric-or-rather-units-agnostic take than most, look around for Byrne’s Euclid. Obviously, you can view it on that site, but its also available in pdf, epub(iirc), and print versions. The print version is just about pocketable, and the concepts are damn near the basis of all maths short-of(and encompassing)Calculous.

    Glad to see this lemmy community revived :D!

    Try the ones listed here: https://github.com/rossant/awesome-math?tab=readme-ov-file#books

    Though I’d agree with another commenter down here, the units largely don’t matter in those subjects and they’re just there to help readers “relate” to the problems discussed in most textbooks, unless you intend to work with, idk, specialized subjects like, something closely related to Physics?
